SAC vs RMV, revisited

As in surface liters, yes. PV = nRT.

Is that a standard unit or just made up ?

Does it have an abbreviation?

Why can’t we use surface cu.ft. ?

By giving units (e.g., miles per gallon, km per liter) no one is confused.

True!

BTW, European mpg convention in metric is a little weird. They use liters / 100 km.

I don't measure my gas consumption in volume per time. I measure my gas consumption in surface volume per time.

As do I, nothing worse than finding out I didn't, makes the ascent too exciting for me.

No, we usually use L/100km. Basically the inverse of your mpg. Units notwithstanding.

Can't you? I'd love if you did, but most of y'all seem to me to insist on using cu.ft/min, pressure be damned.

I think you must have mistaken me with someone else though, because I am French so if I used anything else than litres for volume it was just to continue someone’s else discussion.

I understand the point of using quantity of gas vs volume though I was confused by the earlier post.

most of y'all. This board is rather heavily US-centric.

Actually, most do not do what you say. They start with psi/min at depth, convert that to surface cuft/min. They just don't call it surface cuft.

They just don't call it surface cuft

Which makes for a non-zero amount of confusion. Cite? See upthread.

My bad. I got the units mixed up. Like I said it’s weird way of measuring how much distance you gain per volume of gas.
